ABSTRACT:
The vehicle vibration control system comprises at least two spring constant adjustable engine mounting devices, an engine speed sensor, an engine vibration load sensor, and a controller. The controller controllably adjusts the dynamic spring constants of the engine mounting devices with reference to a stored table and on the basis of detected engine speed and engine load, to cancel vibration transmitted from an engine to the vehicle body via the two engine mounting devices. In the table, theoretically optimum load ratios and phase differences between the two engine mounting devices are listed on the basis of empirical transfer functions between the engine mounting devices and the vehicle body.
